OIS

 OIS stands for Optical Image Stabilization. It is a technology used in cameras and smartphones to reduce or eliminate blurring caused by camera shake or movement. OIS works by using sensors and tiny motors to move the camera lens in the opposite direction of the movement, thereby stabilizing the image and reducing blur. This technology is particularly useful when taking photos or videos in low light conditions or when using zoom lenses, which tend to amplify the effects of camera shake.
